A much easier solution would be to switch over to Electromotives Superblend
software. It allows you to blend TPS and MAP inputs in any ratio at various rpm
through software. Probably beter suited suited to your bike than trying to cram
a MAF sensor in somewhere.

must be the water, every (good) injector I've ever tested had a nice even cone 
shaped pattern.

It might be interesting to try again with fuel but this time blow through
the throttle
body.
